Hello,
I'n trying to get functions like orte-checkpoint, orte-restart,... works but
there are some errors that I don't have any clue about.
Blcr (0.8.2) works fine apparently and I have installed openmpi 1.4.2 from
source with option blcr.
The command
mpirun -np 4 -am ft-enable-cr ./checkpoint_
I think you mean:
mpirun -mca oob_tcp_if_exclude eth0
Actually, it doesn't work.But if I turn down eth0 on the virtual machines (
sudo ifdown eth0), all work like a charm !
Finally, I can start to do something more complicated with openmpi.
Thank you all very much !
Son.
I think the problem reside the orted. As I tested mpirun in 2 virtual
machines(fedora) in Windows, the communication between the two is through eth1
but not eth0. After lauching
ps aux | grep orted
the results is:
/usr/lib/openmpi/bin/orted --daemonize -mca ess env -mca orte_ess_jobid
-1233
d hanging?
Or ...?
Ensure that you have the same version of OMPI installed on both machines and
that both are in your default search PATH for non-interactive logins.
Once you get something like "hostname" to work, it's much more likely that an
MPI application will also work.

ne too.
Thank you in advance!
